    Error 37389: DGFM

    Good evening Mel Is there a way to determine how much memory my simulation will require without actually running the simulation and checking the .out file? I read about --estimate-resource-requirements-only that seems to be what I can use, however I am unclear of how to set up the machines file and what is meant by nodes? For example I wanted to run a Vivaldi array of 13 elements but got an error that stated that there was not enough memory, but not how much memory will be required? Please see the file I am referring to attached. I would appreciate your assistance. Memory_error_files.zip
  3. I'm not sure SimSolid cound do this operation. Keep in mind that SimSolid is not CAD software. So it's better to do CAD operations in CAD software before running SimSolid.
  4. Hi Farouk Do you know any external solver "FAST Frequency Response Solver"? Thanks
  5. Today
  6. Hi Geraldo, FASTFR : This option is used to activate "The faster modal solution method" for modal frequency response analysis ! FFRS : The second means FAST Frequency Response Solver, used if you want to activate the external FASTFRS solver. This solver works well for a large modal frequency response. (You have to install it in advance). FFRSNCPU : used with FFRS. It's useful if you want to define the number of CPUs to be used by the external solver "FAST Frequency Response Solver". FFRSLFREQ : It's a threshold (cut-off frequency) used to partition your system into low freq and high freq. Cheers,
  7. ok i try it as you suggested, after i will update for you the result. thank you very much
  8. Hi Could you help to understand more details, behind online help, about parameters below? Do I need specific lincense for these parameters? Thanks.
  9. HI @Rahul R, I am trying a bottle simulation with radioss, I tried keeping all as simple as possible for simple test. the file says .. ELEMENT BUFFER INITIALIZATION WARNING ID : 312 ** INCOMPATIBLE KINEMATIC CONDITIONS IN MODEL DESCRIPTION : 1 INCOMPATIBLE KINEMATIC CONDITIONS IN MODEL .. GEOMETRY PLOT FILE .. PARALLEL RESTART FILES GENERATION TERMINATION WITH WARNING ------------------ 0 ERROR(S) 1 WARNING(S) PLEASE CHECK LISTING FILE FOR FURTHER DETAILS what shall I do with kinematic conditions? deck_debug_11_0000.rad
  10. I would suggest you try running without the MPI to make sure your model runs. Use the scripts that are included with HyperWorks and run without MPI by using -nt option. <install_dir>/altair/scripts/radioss -nt 8 micro1_0000.rad If this starts to run then you can try using the same script to run using the MPI. Are you running on one node or multiple nodes? For one node, <install_dir>/altair/scripts/radioss -np 8 -mpipath <path to mpirun> micro1_0000.rad Is there a reason why you are using Radioss 13? That is very old. Can you upgrade to a newer version?
  11. Thanks Rahul. PFPANEL(PANEL = ALL,PUNCH) = 80 But Panel participation when exported as punch file, only has exported $REAL-IMAGINARY OUTPUT See this: $TITLE = $SUBTITLE= $LABEL = ROAD_NOISE $PANEL PARTICIPATION FACTORS = PANEL $ITEM = MODAL DISPLACEMENT (REAL/IMAG) $REAL-IMAGINARY OUTPUT $SUBCASE ID = 1 $FREQUENCY = 0.2500000E+00 $GRIDID/COMPONENT = 8000002 $TOTAL RESPONSE = 1.110792E-04 239.62 WIND 6.048552E-04 1.389009E-03 ROOF 4.430148E-04 1.117761E-03 BACK -7.738473E-05 1.025820E-04 ESTERNO -9.413477E-05 -2.086371E-05 CAIXA_R -5.489519E-04 2.624176E-05 CAIXA_L 4.837625E-04 2.274599E-06 PAV_POST -3.835725E-04 -6.275692E-04 PAV_CEN -2.997967E-04 -8.138010E-04 R_DOORS 4.598970E-05 1.128107E-04 F_DOORS 7.701846E-05 1.843218E-04 R_BODY -2.403713E-04 -1.280987E-04 L_BODY 2.846095E-04 2.501589E-04 TUNEL -7.980275E-05 -2.258611E-04 PAV_ANT -3.349108E-04 -9.995590E-04 CRUSC -1.709219E-06 -4.915061E-04 VASCCA 6.521601E-05 2.626772E-05 How do I do to export Panel participation in punch file as MAG / PHASE? I didn't find this online help.
  12. If you are using CAD data, and importing it into MotionView, the CG and MOI will be correctly read into MotionView. You can define it several ways, about the part CG, the vehicle CG, or the global CG, or any other location for that matter. Usually, people will define each part's mass, inertia, and CG location relative to the part, because that's how the data/CAD is defined. You don't have to calculate anything, assuming the CAD is correct. Just define your mass, CG, and inertia the way it is defined in your CAD. The tire forces should be described in our help. In general: f2 = Fx f3 = Fy f4 = Fz f6 = Tx .... It's also pretty easy to sort out the directions by plotting them, and observing the behavior of the forces using simple events.
  13. im sorry, my files named is *.rad, i wrote it wrongly. so what do think the probelm? it seems raleted MPI? i just checked a problem in forum, which is the same with mine, some said it is the MPI issue. you can see it from here thanks again!
  14. Hi, The problems is you have named your files with the *.dat extension but your script is looking for files with *.rad extension. It is typical to use *.rad for Radioss files so I would recommend you change the extension of your files to *.rad. I would also recommend you use a newer version of Radioss than 13 as this is very old.
  15. CGAP, CGAPG, CWELD, CSEAM, CFAST, RBE1, and CONM are not compatible with LGDISP.
  16. Hi, If the deformations go past the values defined in the table, the curve is extrapolated linearly (the slope is taken from the last two data points defined). I think Optistruct does not support rupture (failure), but Radioss does.
  17. Hi, yes is the answer to both questions. /TH/INTER outputs the sum of contact force in contact interface in the time histroy output /ANIM/VECT/CONT and /ANIM/VECT/PCONT outputs the contact forces and/or pessures at nodes in the animation output
  18. I believe local support team is already in touch with you regarding this query. Once resolved, we will copy the final solution in this post.
  19. Please share the .out file of the run?
  20. So you are using true stress/strain curve & set up for MATS1 looks ok to me.To understand your issue in detail, we want some more information related to your model.(.out/.fem/.h3d file)
  21. hello, i have completely situation with (please see the picture i send you), i want ask how to solve MPI issue? this problem troubled me a lot, really need your help! thanks very much shuangshuang
  22. hello, firstly thank you very much your help. i have two files micro1_0000.dat and micro1_0001.dat. firstly i compiled the model in micro1_0000.dat in liunx (you can see the command in capture1), there is no error. after i run it according to micro1_0001.dat (the running command in capture2), it gives me message, "** ERROR : INPUT FILE microl_0001.rad NOT FOUND", and "" ERROR TERMINATION Attempting to use an MPI routine before initializing MPI", as i show you in the pictures last time. thank you very much! this problem is very important for me, thanks again! shuangshuang "
  23. Of course. I attach elso the TABLES1. I imposed the strains between 0 and 1 because shown in the eBook. The real material has maximum total strain equal to 0.3.
  24. Can you please share the settings you defined in MATS1 card?
  25. Hi all, I'm new to SimSolid having previous experience of Ansys and Creo Simulate (ProE). Regarding contact, I'm finding it frustrating that it doesn't seem possible to apply a contact to only part of a surface. For example bonding local to a bolt hole (if the bolt is not included in the model) and applying a separating contact to the remainder of the contacting face. Normally I would split the surface so that I could apply separate contacts but I don't see how to do this in SimSolid. Does anyone know a workaround so that I can apply different contacts to different areas of a surface (or split the surface?). Thanks in advance
  26. Hi everyone, I am simulating tensile tests with welded samples. I am using NLQS analysis in Optistruct, according to the eBook Introduction to Non Linear Finite Element Analysis using Optistruct. My problem is that the stress-displacement curve after the simulation shows stresses which value is higher than the ultimate stress imposed with the TABLES1. How is it possible? Why the stress-displacement curve does not become flat? Does it have any meaning? Bests Martina
  27. Yesterday
  28. Thank you, I am a bit confused, So How do I calculate the inertia values? (FYI- I have a CAD model for my car and the following parts. Do I take the MOI values about the CG of the part OR CG of the vehicle) I am trying to read the data using Hyper Graph 2D and using .plt In the Y components and what does f2, f3, f4 so on means.
